Abstract
The utility model relates to a self-power temp. controlled three-way valve, comprising a temp. controlled three-way valve, a valve rod, a valve core and a valve body. The valve core is tilting and contacted with the three-way pipe of the valve body, and the point of tilting cutoff surface of a drainage pipe is provided with a valve core bar grate and a valve body bar grate. The utility model solves the contradiction that the valve core stroke of single pipe heating system is small, but the requirement of the current cutoff surface is large, and ensures that the self-power temp. controlled three-way valve can move under the state of low stop. The self-power temp. controlled three-way valve is suitable for the enactment and the automatic temp. control of the room temperature of the indoor single pipe heating system, which can increase the reliability of the heat supply of the indoor heating system and the comfort standard of the room, and the utility model can effectively save energy sources.
Description
The utility model self-supporting temperature control three-way valve, it relates to the heating system technical field.
The thermostat valve that is adopted in fields such as HVAC, air-conditioning, heating power at present mainly is the bilateral thermostat valve, be characterized in that spool has very high resistance coefficient (being high resistance type), the effect that is applied to the HVAC variable flow system is fine, and the energy-saving effect in indoor two-tube heating system is also fine.But the indoor heating system of China's extensive application at present is an one-pipe heating system, and it requires thermostat valve must be low-drag type, so existing bilateral thermostat valve can not be satisfied the demand, does not also therefore still have the thermostat valve that is suitable in indoor one-pipe heating system.
Be the deficiency of avoiding above-mentioned prior art to exist, the utility model provides a kind of self-supporting temperature control three-way valve, and it has the lower resistance characteristic, is applicable to indoor one-pipe heating system.
The purpose of this utility model can reach by following measure: the self-supporting temperature control three-way valve that is made of temperature control head, valve rod, spool and valve body, spool tilts tangent with the three-way pipe of valve body, be provided with spool bar grid and valve body bar grid at the scarf place of two outlet pipes, two groups of bar grid are crisscross arranged.End socket is arranged at the valve body bottom that is complementary with spool, and top cover is arranged at top.The valve rod upper end connects with temperature control head, and top cover, spring and spring band are passed in the centre, and the lower end is fixedly connected valve rod and spool with the wing plate on nut and the valve rod.With locknut with temperature control head and externally socket of top cover.
Accompanying drawing is the structural representation of self-supporting temperature control three-way valve
1-temperature control head among the figure, the 2-valve rod, the 3-spool, the 4-valve body,
5-spool bar grid, 6-valve body bar grid, the 7-end socket, the 8-top cover,
The 9-nut, 10-spring, 11-spring band, 12-locknut.
Below in conjunction with drawings and Examples the utility model is described further: the self-supporting temperature control three-way valve is made of temperature control head (1), valve rod (2), spool (3) and valve body (4).The spool of garden tubular (3) tilts tangent with the three-way pipe of valve body (4), establishes spool bar grid (5) and valve body bar grid (6) at the scarf place of two outlet pipes, establishes the valve rod patchhole in the middle of the top board of spool (3), establishes several water budget holes of crossing on every side.End socket (7) is arranged at valve body (4) bottom that is complementary with spool (3), and top cover (8) is arranged at top.The upper end of valve rod (2) connects with temperature control head (1), the lower end is fixedly connected valve rod (2) and spool (3) by the wing plate on nut (9) and the valve rod (2), intermediate portion passes top cover (8), spring (9) and spring band (10), and the upper end of spring (9) is fixed on the valve rod (2).The externally socket of locknut (12) of temperature control head (1) and top cover (8).
Embodiment 1, temperature control head of the present utility model (1) is a prior art, after temperature control head (1) is gone up the room temperature setting, bulb is subjected to the influence of room temperature height and expands or shrink, driving valve rod (2) simultaneously moves up and down vertically together with spool (3), spool bar grid (5) also form thereupon moving up and down and valve body bar grid (6) between slide relative, thereby controlled the current ratio of two water outlets, make valve under any state, the active cross-section sum of the water outlet side all active cross-section with influent side is identical, guarantees that valve can move under low resistive state.
Embodiment 2, and valve body bar grid (6) can adopt the way of lining, promptly are fixed on the valve body at the corresponding position of spool bar grid (5) lining with tape grid.
The utility model has the following advantages compared to existing technology: can be applicable to setting and the automatic constant temperature control of room temperature in the indoor single pipe heating system, improves the reliability of heat-supply system of heating system and the comfort standard in room, and energy savings effectively.
Claims (2)
1, a kind of self-supporting temperature control three-way valve, it is characterized in that it is made of temperature control head (1), valve rod (2), spool (3) and valve body (4), garden tubular spool (3) tilts tangent with the three-way pipe of valve body (4), establish spool bar grid (5) and valve body bar grid (6) at the scarf place of two outlet pipes, two groups of bar grid are crisscross arranged, the part that valve body (4) and spool (3) are complementary, end socket (7) is arranged at its bottom, and top cover (8) is arranged at top.
